Abstract

A bullet or a cartridge containing a bullet having an elongated body with a forward end and an opposed rear end. The body has an intermediate cylindrical portion between the rear and forward ends, and the front end of the body defines a cavity. A resilient nose element is received in the cavity. The nose element may be an elastomer, and may be a cylindrical body. The cavity may be a cylindrical bore, and the nose element may be closely encompassed within the bore. The forward end of the nose element may be flat, and may be flush with the forward end of the body.

Claims

1. A firearm ammunition component comprising:

an elongated body;

the body having a forward end;

the body having a rear end opposite the forward end;

the body having an intermediate cylindrical portion between the rear and forward ends;

the body defining a cavity formed concentrically with the cylindrical portion and open at the forward end of the body;

a nose element, at least a portion of which is received in the cavity; and

wherein the nose element has an exposed front face that includes an identifying indicia on the front face and visible at the open forward end.

2. The firearm ammunition component of claim 1 wherein the nose element is molded with the identifying indicia.

3. The firearm ammunition component of claim 1 wherein the identifying indicia is molded into the nose element.

4. The firearm ammunition component of claim 1 wherein the identifying indicia is a color associated with a brand identity.

5. The firearm ammunition component of claim 1 wherein the identifying indicia is a color indicating a characteristic of the bullet.

6. The firearm ammunition component of claim 1 wherein the identifying indicia is a color indicating a characteristic of a cartridge containing the bullet.

7. The firearm ammunition component of claim 1 wherein the identifying indicia is associated with a manufacturer brand.

8. The firearm ammunition component of claim 1 wherein the identifying indicia is associated with a model identifier.

9. The firearm ammunition component of claim 1 wherein the identifying indicia is associated with a caliber identifier.

10. The firearm ammunition component of claim 1 wherein the nose element is a resilient material.

11. The firearm ammunition component of claim 1 wherein the nose element is an elastomeric material.

12. A round of ammunition comprising:

a projectile portion having a generally circumferential body tapering from a rearward end toward a forward end;

a generally circumferential bore extending from an orifice at the forward end into the body at least part of the way between the forward end and the rearward end;

a polymeric material support surface at the end of the bore opposite the orifice; and

a polymeric material between the polymeric material support surface and the forward end, the polymeric material including a user identifiable marker for allowing a user to identify the projectile portion when viewing the forward end, and the polymeric material having a front face including the marker.

13. The round of ammunition of claim 12, further comprising a bullet case surrounding the rearward end and stopping short of the forward end and a propellant within the bullet case for propelling the projectile portion when the round of ammunition is fired.

14. The round of ammunition of claim 12, wherein the generally circumferential body is located about a circumferential axis and a center of the generally circumferential bore is on the axis.

15. The round of ammunition of claim 12, wherein the polymeric material support surface is generally parallel to the surface surrounding the orifice.

16. The round of ammunition of claim 12, wherein the user identifiable marker is a front face of a cylindrical body located in the bore and covered with the polymeric material.

17. The round of ammunition of claim 16, wherein the user identifiable marker includes a top surface facing the orifice and a user identifiable mark is on the top surface.
